Description
尚、以上説明した従来のプロペラファンの形状や製造方法については、例えば、特許文献1における従来技術の説明に記載されている。
付根部の幅方向に対して直交する方向となる。従って、羽根の付根部の強度が向上し、より耐久性を高めたプロペラファンを提供することができる。
尚、各ゲート9a,9bおよび9cは、それぞれゲート痕7a、7bおよび7cと対応する位置となるよう、金型に設けられる。
2 ハブ
3 羽根
3c 前縁
3d 後縁
4 ボス
5 周壁
6 端面壁
7、7a〜7e ゲート痕
8 ランナー部
8a 分配部
9、9a〜9e ゲート
20 付根部
30 長繊維
40、40a〜40i 樹脂の流れ
Claims (5)
- 端面壁と周壁とからなるハブと、同ハブの外周に複数枚の羽根を備え、長繊維を含有する樹脂材を用いた射出成形によって成形されたプロペラファンであって、
